vApplication filed M ay 12, 1910. Serial No. 560,812.

Be it known that we, HENRY J. GRAF and Tmiononn Giur, citizens. of the United States, and residents of Louisville, Jefferson county, Kentucky, have invented certain e newr and useful Improvements in Molding- Flasks, of which the following is a specification containing a full, clear, and exact description, 'reference being had to the accompanying drawings, forming a part hereo Our invention relates to improvement-s in molding flasks and is particularly directed to the construction orf the hinge members for the cope and diag as well as a hinge member for the match plate.

The primary object of our invention isv to, construct hinge members for the cope, drag and match plate which will permit of the rolling upof thencope and match plate,

which hinge members are provided withA guides for the purpose of directing the cope 'and match plate to perfect registering positions and which' hinge members permit the match plate to registering posit-ions.

ready withdrawal or removal ofthe match plate.

Heietofore in the molding o f castings with-'match plates, the cope and-the match plate were lifted or drawn from the drag and there were guide pins on the flask for the purpose of guiding the cope and the This lifting or drawing the cope required some considerable skill on the part of the molder and if the flask was of any great size the niolder required assistance, due to the weight of the cope.

For the above purposes our invention conslsts in certain novel features of construc- L tion and arrangement of parts as will be hereinafter more fully described, pointed out in the claims and illustrated by the ac companying drawings, in which:

5 is'a transverse, sectional e eration taken on the line 5-5 of Fig. 3:; Fig. 6 is a transverse, sectional elevation *illustratingthe hinge members as when employed with the match plate; Fig. T is a view similar to 60 .Fig 6 with the match plate removed; and F ig. S is a transverse. sectional elevation of. the cope and drag hinge members taken on a line through the journal bearing for the hinge plate of the match plate.

Referring by numerals to the accompany'- ing drawings: l designates the drag which maybe of ordinary construction.

2 designates the cope which may be of ordinary construction.

3 designates the match plate which is of ordinarv construction except for the cut away portions 4, the margins of which cut away portions are reduced for approximately one halt' the thickness of the plate 75 and which reduced margin is designated by the numeral 6 designates the'vhinge members for the match plate' which. in general appearance resemble, rectangular plates, the inner margin and both end margins of the hinge plate are reduced, which reduced portions are designatedvby the numeral 7 and which reduced Y portions are arranged to lit the reduced portions of the match plate.

8 designates threaded apertures formed in the reduced portions T, which are ar ranged to receive the screws 9, which screwsl are inserted through apertures formed through the reduced portions 5 of the match 90 plate and seated 4in the apertures 8 to securely hold'the hinge plates 6 in place.

In each of the hinge pla-tes 6 there'is formed a. rectangular opening 10 and formed in alineineiit with the opening 10 95 there is a marginal extension 11, the edge of which marginal extension is preferably rounded.

12 designates an integral, semicircular marginal extension formed on each of the plates G adjacent the end of the plates opposite the marginal extension 11,'the extension 12beiiig of less thickness than the plate 6 proper, the materialof the late,

about its margin on top of the extension 12, y

being removed and the upper face ofthe extension 12 being provided with 'a depres-4 sion 13.

The hinge plates 6 are exact counterparts of eachother except for the arrangement 'of the parts to. adapt them to right or left hand sides.

14 and 15 designate the body portions of the drag hinge members, the bases of which are substantially of the shape of rectangular plates which are secured to the side member of the drag by the screws 16, the heads of which are llush ith thc upper faces of the `hinge members r hen fully seated.

i its upper faces V-shape in cross section.

Formed in thc face of cach body portion in alinement with the hooks 18 are the depressions 19.

'.20 designates integral bosses formed ou the upper faces o f the plates 14 and 15 which are spaced slightly apartand which form a bearing for the journal formed by the marginal extension 11 of the hinge Aplate of the match plate, the body portions 14 and 15 together with the hooks 18 and bosses 20 forming the hinge members for the drag and are the exact counterpart of each other ex -cep't for the location of the bosses..20.

v2l and 22 designate the body portions of the hinfre members for the cope 4which are secnli` screws 23.

24 designates marginal, up-turnedianges i formed integral with t'he body portions, the inside faces of which areA ush. with theA outside margins of the body portions 21 and 22. Y

*25 designates the hinge member proper which is formed integral with the. `flanges 24, the body portion of which, as shown in Figs. 6 and 7, is substantially circular. f

26 designates integral guides, the inside faces of which incline from the body portion 25 outwardly and are shaped to conform with the upper faces of the hooks' 18.

On the end faceof each of the bodyl portions 21 and 22 and in alinement with the body 25 of the hinge there is a boss or guide pin 27 ararnged to seat'in the depressions 13 formed-in the hinge plates of theA match plate'or in the depressions 19 in the drag hinge members when the ,match ,plate is ed to the cope by means of the removed. As shown, each of the body p01- tions 21 and 22 is cut away at 28'to form a space to accommodate theoutermost bosses 20 carried by the drag hinges.

The flask, as described,1semployed gen! flask except forv the fiaskhmfing hinges, as shown, the cope may be rolled up and the match plate may be rolled up, there being guides both on the hinge members of the cope and drag as well as on the hinge members of the match plate to assure perfect registering of parts at all times, no other guiding means, suoli as pins in the ordinary flasks, being employed.

`We claim: Y

1.A In a molding flask, the combination with means for hingedly connecting the cope and drag, which means are provlded with coperating guides which assure registration ot' the cope and drag when placed in operative positions, a. match plate detachably, hingedly connected with the hinging means of the cope and drag and-a guideA carried by the match plate arranged to coac't with the otherguides.

2. In a molding flask, a drag, hinge members secured to the drag, guides arranged on said hinge members, a cope, hinge members carriedby the cope, guidesl on said hinge members, a match plate, detachable hinge members 'carried by said match plate' and guides on said detachable hinge'members which coperate With-the guides on the. drag and co e hinge lmembers for holdin .the

parts o the mold in registration when c osed.

In testimony whereof, we' have signed our names to this specification, in presence of two subscribing Witnesses'.
